At one time, the Texas Horned Lizard was a common denizen of North Texas. My sister would catch them and dress them up in baby doll clothes (and release them at the end of the day).
Unfortunately, the invading fire ants displaced their natural diet of harvester ants. Insecticides used to fight the fire ants also caused the horned lizard population to decline.
Currently the horned lizard is considered a threatened species. Owning or possessing one is a big no-no.
That's a shame, because they're really cool.
I found this model on the Digimorph site. Lots of cool data there.
Horny Toad Grey
Pcornutum.stl - The original file from Digimorph. This has all the internal details of the horned lizard. Tongue, ears, sinuses, etc. Not really suitable for printing, but here it is.
Horny_toad.stl - Cleaned up model. All internal structure eliminated so it doesn't slow down the print. Also, did a little sculpting on the eyes so they are open (the lizard used in the CT scan was deceased.)
Horny_plaque.stl - The plaque to mount your fine horny toad model on, if you choose.
You choose the scale of the model. If you want life size, that's the present size of the models. If you want a fridge magnet, x2 or x4 is good. If you want a wall mount, you'll have to decide for yourself how large you can print. Scale the head and plaque accordingly.
Fill, sand, prime, paint. You'll have to decide how you want the model to look.
I was unable to get the nice dark brown stripe below their eyes. Either an air brush or a sponge might be the way to go.
Glue the head to the plaque.
Hang it in a prominent place such as in your office.
A fine fridge magnet.
